CONTAINER NOZZLE AND CLOSURE THEREFOR Application filed June a, 1929. Serial No. 367,974.

This invention relates to nozzles for containers, and morefparticularly to the means 7.

j for sealing the said nozzles. It is the general purpose and object of the invention to provide a cooperating construction of nozzle and closure means thereforwhich will enable the said closure means to be quickly applied to and conveniently removed from the nozzle and which, through the application of the closure means, will result in compacting the gasket forming part-of such means against the end of the nozzle, thereby: to provide a tight and leak-proof joint The invention is adapted for use with nozzles having a downwardly-directedskirt within the outer bodyof the nozzle, such A skirt usually being-formed by "rolling or bend- I to Fig. 1; Fig. 3 a plan View of the nozzle;

ing the outer'end ofthe nozzle inwardly and downwardly.

The invention herein isv disclosed in the drawings forming part hereof wherein Fig. 1 represents a sectional'vi'ew through the top of the receptacle and its'nozzle and the closurerneans therefor; Fig. 2 a view of the nozzle and closure'means similar to Fig. 1, the sectional view being taken at. right angles Fig. 4 a bottom plan view of the closure for said nozzle; and Fig. 5 a sectional view of the top of the nozzle, the section corresponding to that .on which Fig. 1 is taken. Y

In the said drawings, 1 represents a container', preferably of sheet metal, and having thereon a nozzle comprising the body 2 and :the inwardly and downwardly directed upper edge portion 8. The bead which is thus formed by such edge portion is provided at' the bottom of its inner edge with a plurality of inwardly extending lugs 4 formed integral with the metal of which the nozzle is composed. Two such lugs are shown,,although the number may be varied as desired.

7 Cooperating with the aforesaid nozzle is a closure, the said closure'being in the form of a cap having an outer and upper annular portion 5 between which and the top of the head there is interposed a gasket 6 of resilient compressible material, such as rubber, cork, or The cap comprises, in addition to the outer annular portion 5, a

I claim isr' cup 7,the outer diameter of which is such 7 as to enablethe cup to be slipped between the lugszl with its bottom projecting below the i same. The cup is provided with a plurality thread segments, which segments are arranged to cooperate with the lugs 4 when the closure is rotated inthe appropriate direction, thereby to draw the closure clownwardly and compress the gasket againstthe top of thenozzl'e. By rotating the closure in the reverse direction, it will be obvious that the thread segments will disengage the lugs andthat theclosurem'ay be removed.
